The invention discloses a ceramic material with a high piezoelectric property and a preparation method of the ceramic material. The ceramic material with the high piezoelectric property is prepared from components in parts by weight as follows: 60-75 parts of zirconium dioxide, 20-25 parts of magnesium oxide, 2-3 parts of antimony trioxide, 2-3 parts of antimony mercaptide, 1-2 parts of silicon dioxide, 0.5-1 part of cobaltous sulfide, 0.5-1 part of lead titanate and 0.05-0.5 parts of potassium nitrite. The invention also provides the preparation method of the ceramic material with the high piezoelectric property. The method comprises steps as follows: (1) 60-75 parts by weight of zirconium dioxide, 20-25 parts by weight of magnesium oxide, 2-3 parts by weight of antimony trioxide, 2-3 parts by weight of antimony mercaptide, 1-2 parts by weight of silicon dioxide, 0.5-1 part by weight of cobaltous sulfide, 0.5-1 part by weight of lead titanate and 0-1 part by weight of copper are weighed and stirred uniformly at a high speed; (2) 0.05-0.5 parts by weight of potassium nitrite subjected to sufficient ball milling are sequentially added to a product obtained in the step 1, spray granulation and pressing forming are performed, a product is sintered at the temperature of 1,250-1,280 DEG C for 2-3 hours, and the ceramic material with the high piezoelectric property is obtained.
